UnicodeDecodeError with pip installing anything

[JWDobken]

• Pip version: 9.0.1
• Python version: 3.6 (miniconda)
• Operating system: Ubuntu 16.04.3 LTS

Description:

I am trying to install any package with pip, but this gives me a UnicodeDecodeError. Strangely this does work in the main user directory, but not in a python package directory.

What I've run:

For example update pip itself:

pip install -U pip

Returns:

Requirement already up-to-date: pip in /home/USER/miniconda3/envs/PYENV/lib/python3.6/site-packages
Exception:
Traceback (most recent call last):

    self._read(fp, filename)

    return codecs.ascii_decode(input, self.errors)[0]
UnicodeDecodeError: 'ascii' codec can't decode byte 0xc3 in position 104: ordinal not in range(128)

Notes

• the directory name does not contain non-ascii characters as suggested here. It contains lowercase letters and dashes ("-").
• which pip from the main and sub directory return the same pip (/home/USER/miniconda3/envs/PYENV/bin/pip)
• if I make a non-python-package directory who's name only contains lowercase letters and dashes ("-") there is no error (like "test-this-name").

So I found the cause of the issue.

I was not aware that pip would read the file setup.py, but apparently it does.
This file contains my surname with an umlaut (ö), so replacing it solved to issue... for now.

This umlaut has been there forever and until last week never caused this error.

Hi! Thanks for filing this issue!

Could you take a look and determine if this is still an issue with the latest master?

Closing due to a lack of a response.

@pradyunsg Yes, there is.
I tried running pre-commit with pyenv enabled and I am getting the same error.

Environment:
pip 18.1
pyenv 1.2.7
pre-commit 1.11.2

Below is the stack trace:

You are using pip version 10.0.1, however version 18.1 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.
